Description

The present invention relates to a tilting vertical window moving balance device.

[Conventional technology]

In a tiltable up-and-down moving window, a balancing device having a balancing means for window shoji and a means for adjusting the balancing force of the means, and a braking force to the window shoji when the balancing means and the window shovel are tilted. Balancing devices are known which are provided with braking means for applying and fixing in that position.

[Problems to be Solved by the Invention]

In the above-mentioned conventional balancing apparatus, the former lacks braking means, so when the window shoji that is in balance with the balancing means is tilted, the balance breaks, and the lifting force of the hanging means reduces the shoji pulling force. As it becomes relatively larger, the shoji rises,
Also, the latter lacks the adjusting means, so that it is not possible to adjust the balancing means after assembling the balancing means and the shoji in the window frame and the change in the force of the balancing means due to use. There was also a problem with things.

According to the present invention, the adjusting means for the vertically movable window can be adjusted even when the window shoji and the balancing means are assembled to the window frame, and when the window shoji is tilted, the shoji is restrained. It is an object of the present invention to provide a convenient balancing device in which power is automatically applied to maintain the balance of window shoji.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention comprises a balancing means for window shoji and a sliding body which can be moved up and down along a vertical frame of a window frame and which is hung by the balancing means and supports the window shoji. A means for adjusting the balancing force of the balancing means for the sliding body and a braking means for automatically braking the sliding body in accordance with the tilting of the window screen are incorporated.
